Abstract
The invention relates to a sizing material environmental aging simulation test method, which comprises the following steps: 1) vulcanizing the rubber material, and cutting; 2) bonding the cut rubber sheet to the central part of the groove of the rim; 3) mounting a tire matched with the rim in size to obtain a tire, rim and film combination; 4) filling compressed air into the tire, if the tire is not air-leakage and is parked for more than 24 hours at the ambient temperature, replacing the compressed air in the tire with nitrogen-oxygen mixed air; 5) placing the tire, rim and film combination into an aging box, aging for eight weeks at 65 ℃, wherein nitrogen-oxygen mixed gas is refilled every two weeks; 6) and (4) after the steps are finished, removing the tire, and taking the film off the rim for detecting the related physical properties. Has the advantages that: the simulation test of the environmental aging of the rubber material can be directly used for the environmental aging test of the rubber material, and has good correlation, simple method and wide application range.
Description
Technical field
The present invention relates to a kind of sizing material environmental aging analog detection method.
Background technology
Tire environmental aging is also known as thermo-oxidative ageing, the effect that its mechanism of action is heat will accelerate the chemical changes such as elastomeric material crosslinking degraded, macro manifestations is that physical and mechanical properties changes, some performance and ageing time are single variation relation, such as elongation at break, stress relaxation coefficient, compression set rate etc..
Tire uses the time longer in actual use, in using often through being heated, the effect of the extraneous factor such as light, nitrogen oxygen, ozone, by the chemical composition of elastomeric material, the factor such as molecular structure and cause the change of rubber physical performance, this is a kind of irreversible chemical change.Rubber is once aging not only tire appearance there will be full of cracks, and tire tread glue is not wear-resisting, easy stabbing, it is easy to collapses and uses up soon, and the carcass of tire is easy to because compound physical hydraulic performance decline causes carcass to come to nothing, thus has a strong impact on the serviceability of tire.Therefore must first carrying out the condition simulation Acceleration study higher than using environmental requirement, in prior art, conventional two kinds of methods once are simulated Acceleration study:
Method one: tire is filled on wheel rim, after pouring 50/50 nitrogen oxygen mixed gas, tire and rim combination are put in the ageing oven of certain steady temperature, and the assembly requiring every 1 week or 2 weeks to take out tire and wheel rim, the change of its air pressure and oxygen content is measured after being cooled to uniform temperature, after again pour new nitrogen oxygen mixed gas to accelerate the change of tire, total duration is 7 weeks or 8 weeks.After off-test, check tire appearance change, and do relevant physical property detection.
Method two: the rubber test piece vulcanizated is directly placed in ageing oven, it is desirable to ageing oven to have thermostatic, exhaust apparatus.Put into the interval having 50mm between the sample of case, pour oxygen, and add pressure test in heating, temperature is generally heated to 70 DEG C of oxygen pressures and is maintained at 0.6-07mpa, persistent period selects in 24h, 48h, 72h, after the time of regulation, after at room temperature parking 16-96h, the related physical performance of re-test sizing material.
Detection method of the prior art has limitation (cannot do sizing material aging) and expensive, needs professional to detect, and the testing time is long simultaneously.Wherein can only doing the environmental aging experiment of finished tire in method one, method two can do the environmental aging experiment of sizing material, but is only limited to hot air aging.
Therefore, it is necessary to propose effective technical scheme, solve the problems referred to above.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, it is provided that the sizing material environmental aging analog detection method that a kind of device simple, cost are low.
The technical scheme is that
A kind of sizing material environmental aging analog detection method, step is as follows:
1) sizing material being vulcanized, the inventive method can simulation test different formulations sizing material environmental aging；And the film after having vulcanized can carry out cutting (such as dumbbell shape sample, rectangular specimen) according to different test items；
2) film after cutting is bonded to the groove centre of wheel rim, and sample is uniformly at intervals in described wheel rim；And each film can not contact with wheel rim, interval 50mm between each film；
3) tire matched with described rim size is installed, obtain tire, wheel rim and set of films fit；
4) tire will pour compression air, the tire assembled is put in water tank at least 30 minutes, check whether tyre bead and valve cock place leak gas, as parked more than 24 hours at ambient temperature without gas leak phenomenon, compression air displacement in tire is become nitrogen oxygen atmosphere (air pressure selects according to tire sidewall allowable stress, is adjusted with specific reference to experiment needs)；
5) putting in ageing oven by above-mentioned tire, wheel rim and set of films zoarium, 65 DEG C aging eight weeks, wherein within every two weeks, re-fills nitrogen oxygen atmosphere once；
6) after above-mentioned steps terminates, pull down tire, film is detected as related property from taking off wheel rim.
Beneficial effect: sizing material environmental aging simulation test of the present invention is first carry out the condition simulation Acceleration study higher than using environmental requirement, the present invention can be made directly the environmental aging test of sizing material, possesses good dependency, and method is simple, and has wide range of applications.
